In use, when puggaree 71 is expanded gradually, puggaree 71 drives many simultaneously and props open pole 72 and launch around the vertical axis 61 rotation, between this, many prop open the inner of pole 72 and launch in annular groove 541 internal rotation, first dog 721, second dog 722 card respectively in the both sides position department of annular plate 54, in order to fix a position the radial distance between the inner of propping open pole 72 to the vertical axis 61, avoid propping open the unexpected annular plate 54 that breaks away from in the inner of pole 72, thereby ensure that many prop open the pole 72 and launch the back and distribute along the circumferencial direction of vertical axis 61, and then make a plurality of poles 72 that prop open and can form circular structure after driving puggaree 71 and launch.

As shown in fig. 7, 8, 13, before the right-hand member of locating lever 73, first detecting head 732 and second detecting head 731 are installed respectively to the rear side, still include control module, first voice broadcast module and second voice broadcast module, first voice broadcast module, the second voice broadcast module, first detecting head 732, second detecting head 731, first motor 2, second motor 4, third motor 6 all and control module between electric connection, first detecting head 732, electric connection between the first voice broadcast module, second detecting head 731, electric connection between the second voice broadcast module.

When the bracket is required to be unfolded, the control module firstly controls the first motor 2 to rotate, then controls the second motor 4 to rotate, and finally controls the third motor 6 to rotate, so that the first bracket, the second bracket and the mounting bracket 5 are completely unfolded in sequence, and the collision condition among parts is avoided during unfolding; when the second detecting head 731 detects that the stretching rod 72 is stretched, at this time, the sunshade cloth 71 is completely unfolded, and the control module controls the second voice broadcast module to send out a voice prompt, for example, the prompt tone may be "sunshade success"; when first detecting head 732 detects to prop up open the pole 72, puggaree 71 is by the complete shrink, and voice prompt is sent out to the first voice broadcast module of control module control, for example, the prompt tone can be for "the sunshade finishes", can remind the timely understanding operational aspect of user, and is more intelligent, it is more convenient to use.

In addition, the invention also discloses a using method of the automatic sun-shading device for the electric baby carrier, which comprises the following steps:

s1: starting the first motor 2, wherein an output shaft of the first motor 2 drives the second bracket 3 to rotate upwards by 180 degrees to be in a vertical state;

s2: starting the second motor 4, wherein an output shaft of the second motor 4 drives the mounting frame 5 to rotate to the right by 270 degrees to be in a horizontal state;

s3: the third motor 6 is started, the output shaft of the third motor 6 drives the plurality of opening rods 72 to rotate and unfold through the vertical shaft 61, and the plurality of opening rods 72 drive the sunshade cloth 71 to unfold to form a circular structure;

s4: when the second detecting head 731 detects that the opening rod 72 is opened, the second voice broadcasting module is opened and a prompt voice of "successful sun-shading" is broadcasted.

The foregoing is a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
